ANCHOR FOR BUILDINGS.

- SPECIFICATION forming part of Letters Patent No. 436,767, datedSeptember 23, 1890.

Application filed June 28, 1890. Serial No. 357,126. (No model.)

To aZZ whom it may concern:

Be it known that I, IVILLARD D. BAKER, a citizen of the .United States,residing at Rogers, in the county of Benton and State of Arkansas, haveinvented a new and useful Anchor for Buildings, of which the followingis a specification.

This invention has relation to improvements in anchors for buildings andvarious kinds of masonry adapted for connecting to the same of variouskinds of beams, joists, &c.

A further object of the invention is to provide an anchor adapted forinsertion in the most rigid manner into old walls at the side of whichnew buildings are being erected, and for connecting to the same joistsof said building, whereby the new walls maybe permitted to settle,subsequent to their erection, without injury or strain either tothemselves or to the old wall.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a perspective of an old wall inwhich has been set a joist and an anchor. Fig. 2 is a transversevertical section through the anchor and wall. Fig. 3 is a horizontalsection of an old wall having an anchor constructed in accordance withmy invention and connected thereby to a new partition-wall. Fig. 4 is aperspective in detail of the two anchor-sections and the wedge.

Like numerals indicate like parts in all the figures of the drawings.

The improved anchor is formed of opposite halves or sections 1 ofexactly similar construction, the two sections being designed to bemounted one upon the other, and the in:

ner faces of the two sections are correspondingly recessed in diagonaldirections, as at 2, for the purpose of receiving a locking-key,hereinafter described. The upper and lower outer corners of the sectionsare provided with ontwardly-proj ecting perforated anchoring ears orlugs 3, the perforation 4 of the upper lug aligning with thecorresponding perforation of the lower lug.

It is well known among builders and others conversant with theconstruction. of masonry that wedges driven between bricks or stoneswill burst the same long previous to the time that the actualcrushing-power of the bricks or stone has been reached, and that,therefore, such means for anchoring beams, &c., are impracticable. By myinvention, however, I overcome this difliculty, and yet secure the fulladvantage of the wedge.

5 represents an old wall in which rests one end of a joist 6, theopposite end of the joist presumably resting in a new wall of a structure being erected at one side of said old wall; At one side of the joista brick and two layers of mortar are removed, forming a recess 7. In therecess 7 is located the anchor, heretofore described, which may beformed of cast metal or in any desired manner. Between the twoanchor-sections is driven a wedgeshaped key S, of hard wood, and whichis, as before stated, slightly tapered or wedge shaped, and its oppositelongitudinal sides are parallel and formed upon diagonal lines, asshown, so that said key conforms in shape to the intermediate recess orsocket formed by the combined anchor-sections. To one side of the joistthere is securely bolted a strap 9, which strap terminates at its freeend in an eye 10. A bolt 11 is passed through the vertical opposite eyesof the lugs of the anchor-sections, and to said bolt is connected oneend of a connecting-rod 12, the opposite end of said rod looselyconnecting with the eye 10 of the strap. In this manner it is apparentthat joists, girders, 850., may be connected to walls of masonry,whether formed of brick or stone, and a settling of the opposite end ofthe same will not strain or affect the old wall to which the joists areanchored.

In Fig. 3 I have illustrated how a new partition-wall may be anchored toan old wall. In the present instance the anchor is set into the old wallin the same manner as previously described. 13 represents thepartition-wall, the central course of brick for a short distanceadjacent to the old wall being cut away to form a narrow recess 15, andsaid central course terminates slightly in rear of the end of thepartition wall, forming a recess 16. A plate 17 is located at the rearend of the narrow recess 15, and in the same is formed a perforationthrough which is inserted a conmeeting-rod 18, the rearend of which isheaded to prevent the rod being drawn through the hole in the plate. Theinner end of the rod is provided with a hook 19, which engages the boltof the anchor, the lugs of said anchor taking into the recess 16, asclearly shown.

By the above construction it will beapparent that I have provided a verysimple, cheap, and efficient anchorage, one capable of use forsupporting joists, beams, stairways, and in all styles of masonry, whichanchorage is capable of being keyed into position so as to receive thefull benefit of the wedge-shaped key without imparting the injuriouseffect of the force of the same upon the masonry, as heretofore done.

Having described my invention, what I claim is l. The combination, witha wall having a recess, and a joist or its equivalent projecting fromthe Wall, of an anchor formed of opposite sections or plates terminatingat their front ends in perforated lugs, a connecting-bolt mounted in theperforations and loosely connected with the said joist, and awedge-shaped key driven between said plates, substantially as specified.

2. The combination, with a wall having a recess, a joist, beam, or itsequivalent projecting from the wall, of an anchor formed of oppositehalves or sections terminating at their front ends in perforated lugsand having their inner faces diagonally and correspondingly recessed, awedge shaped and diagonally-disposed key driven in said recess andbetween the sections, a bolt mounted in the perforated lugs, astrapbolted to the joist, and a connecting-bar terminating in hooks andengaging an eye at the free end of the strap and the bolt of the anchor,substan tially as specified.

3. The combination, with a wall having a recess, of an anchor formed ofopposite plates or sections having their inner faces recessed, aWedge-shaped key inserted in said recess between the plates, aWall-joist or its described equivalent abutting against thefirstmentioned wall, and devices for connecting said Wall-joist or itsdescribed equivalent with the anchor, substantially as specified.

t. The herein-described anchor, comprising the opposite plates orsections fitted in the wall, the wedge-shaped key inserted between theplates, and the connecting-rod attached to the plates and to the sidewall, substantially as specified.

In testimony that I claim the foregoing as my oWn I have hereto aiiixedmy signature in presence of two witnesses.
